This book is a welcome edition to the Particle Technology Series,
formerly Powder Technology Series. It is the second book in the series
which describes powder mixing and we make no excuses for that. The topic
of powder mixing is fundamental to powder technology and is one which
always aroses interest. That will not change. As powder products become
more complex they will pose new mixing problems. The solutions lie in
the intelligent use of equipment, an understanding of powder properties
and a good knowledge of basic statistics. The authors of this book have
presented those three ingredients with great clarity. The book is based
on long experience and deep thought, I have enjoyed reading it and am
pleased to recommend it. Delft University of Technology, NL-Delft, July

Edition In response to many enquiries from industrial organisations and
institutes involved with the technology of processing bulk materials, we
are pleased to present the English edition, Mixing of Solids. The text
is based on the first edition written in the German language Mischen von
Schiittgiitern [1]. The English version has been revised and updated
to include the most recent re- search developments, the conclusions of
which have been taken into account.
